The UN proposed 30% of land and sea is preserved for species in danger of extinctionby 2030 (there are several measures in it addressing pollution, etc) but, although there will be countries (most likely, Europe, Canada, etc) that will at least try, I am very skeptical anything will be done here in USA because we have gone back instead of forward.
